  • SULFUR-CONTAINING COMPOUNDS AND POLYMERS AND THE USE THEREOF IN ELECTROCHEMICAL CELLS
    Publication number: 20230064888
    Abstract: The present technology relates to a sulfur-containing polymer or organic compound for use in a positive electrode material, especially in lithium batteries. More specifically, the use of this sulfur-containing polymer or compound as an active electrode material makes it possible to combine sulfur and an active organic cathode material. The present technology also relates to the use of the sulfur-containing polymer or organic compound as defined herein as a solid polymer electrolyte (SPE) or as an additive for electrolyte, especially in lithium batteries.
    Type: Application
    Filed: August 25, 2022
